Textile Organic Dyes –
Characteristics, Polluting Effects and
Separation/Elimination Procedures from
Industrial Effluents – A Critical Overview

1. Introduction
The residual dyes from different sources (e.g., textile industries, paper and pulp industries, dye and dye intermediates industries, pharmaceutical industries, tannery, and Kraft bleaching industries, etc.) are considered a wide variety of organic pollutants introduced into the natural water resources or wastewater treatment systems.
One of the main sources with severe pollution problems worldwide is the textile industry and its dye-containing wastewaters (i.e. 10,000 different textile dyes with an estimated annual production of 7.105 metric tonnes are commercially available worldwide; 30% of these dyes are used in excess of 1,000 tonnes per annum, and 90% of the textile products are used at the level of 100 tonnes per annum or less) (Baban et al., 2010; Robinson et al., 2001;
Soloman et al., 2009). 10-25% of textile dyes are lost during the dyeing process, and 2-20% are directly discharged as aqueous effluents in different environmental components.
In particular, the discharge of dye-containing effluents into the water environment is undesirable, not only because of their colour, but also because many of dyes released and their breakdown products are toxic, carcinogenic or mutagenic to life forms mainly because of carcinogens, such as benzidine, naphthalene and other aromatic compounds (Suteu et al.,
2009; Zaharia et al., 2009). Without adequate treatment these dyes can remain in the environment for a long period of time. For instance, the half-life of hydrolysed Reactive Blue
19 is about 46 years at pH 7 and 25°C (Hao et al., 2000).
In addition to the aforementioned problems, the textile industry consumes large amounts of

Folk etymology has it as originating from French ‘corde du roi’ (King’s cord), but in French the term for the cloth is velours À côtes, thus casting doubts on its French origin. Some Historians believe that before being called corduroy, this fabric was frequently known as “fustian”, named after the Egyptian town where it originated. Yet other scholars have found linkages of the word to American and Latin origins. So far there is no substantiated…

Unfortunately, because of this, tons of textiles end up in landfills, rather than at recycling centers. By recycling textiles, we reduce the amount of energy that is required to produce the fabrics, since much of the production is already done. Also, recycling helps conserve precious resources. Many don't relise how much energy…
